| Question | Answer |
|---|---|
| he declared all animals are made up of cells in 1839 | theordor schwann |
| he was the first to look at live cells in pond water in 1675 | anto van leeuwenhoek |
| in 1838 he stated that all plants are made up of cells | matthais schleidon |
| he looked at cork cells in 1665, he called them cells | Robert hooke |
| this German doctor stated that at cells come only from existing cells | Rudolph virchow |
| a cells shape is determined by what? | cells function |
| the surface area to volume ratio is the limiting factor of cells what? | size |
| which type of cell had DNA unprotected in the cytoplasm? | prokaryotic cells |
| which type of cell has a nucleus and membrane bound organelles | eukaryotic cell |
| life is estimated to be 3.5 million years old. what type of cell is formed first? | prokaryotic cell |
| which four structures are found in prokaryotes and eukaryotes | cell membrane, cytoplasm, ribosome, DNA |
| what does a eukaryotic cell use for a shape and support of its organelles | cytoskeleton |
| what are the two parts of the sytoskeleton? | microtubules and microfilaments |
| which structure is in a eukaryotic cell and is used for rapid movement in that cell | endoplasmic reitculum |
| what three eukaryotic cell parts can be found in plant cells but not in animal cells? | cell wall, chloroplast, large central vacuole |
| which molecules hold the code from the building of proteins | dna |
| which organelle is the site of protein synthesis (protein factory) in both eukaryotic and prokaryotic cells | ribosome |
| which organelle has the inner membrane folded into cristae and produces ATP energy for the cell | mitochondria |
| which organelle can take up 90% of the interior of a plant cell | vacuole |
| which organelle, found only in plants, captures light energy and changed it into chemical energy in the form of sugar (glucose) | chloroplast |
| carbonhydrates are burned in the mitochondria to produce this energy molecule | ATP |
| what is another name for a lipid membrane sac that stores materials, transport materials, and provide a chamber for biochemical reactions? | vesicles |
| which structure inside the nucleus builds ribosome parts to be assembled in the cytoplasm | nucleolus |
| list all organelles that participate in protein production and transport | ribosome, endoplasmic reticulum, golgi apparatus, vesicles |
| which organelle, located outside the cell membrane, do plants have for the stregnth and support which is not found in animal cells. | cell wall |
| in which type of cells can multicellular organisms can be found | eukaryotic |
| what is the main function of a cells nucleus | protects the DNA |
| which organelle acts as a recycling center, breaking down old cell parts | lysosome |
| 3 parts of cell theory | 1. all living things are made up of one or more cells. 2. cells are the basic units of structure and function in organisms. 3. cells only come from existing cells. |
